Lightbulb Conundrum - Drinks, Anyone?
A pint is yours if you can solve this conundrum for me (a theoretical explanation you can convince me of will do; I have a practical workaround).
A few weeks ago I replaced some of the bulbs in my house with energy-saving ones. However, the ceiling light in my hall behaves in a very odd manner. Occasionally, after I switch it off at the wall, it flickers on very briefly (for about 1/10 second) about once every minute - even though the power is (allegedly) off. The flicker is fairly dim, so I only notice it at night. If I take the bulb out of the socket, the flicker stops. If I put it back, it starts again. This behaviour happily continues for hours - to the extent that I remove the bulb when it happens because it’s too distracting when trying to sleep.
